Buy these, buy these buy these!
Yes, I'll buy them again, and if I were you, I'd buy these too.
I have a 3 kg machine, and just one of these small tablets is enough for a full load, and everything comes out surprisingly clean and smelling great. The pleasant smell persists even after using a drier.
I usually take one or two articles and hang them to dry in my bedroom and the whole room smells great.
At £7.20 these are a bargain, as the cost over £10 at Tesco.
